Run LowpanManager on BackgroundThread

The ConnectivityThread class is being separated into a specific
connectivity JAR; transport-specific managers like LowpanManager should
not be sharing the ConnectivityThread.

As callbacks from ILowpanManager / ILowpanManagerListener already do not
have any ordering guarantee with ConnectivityManager callbacks, the
impact of this change should be minimal.

LowpanManager is unused in AOSP, and not part of the API.
